R package developer (and R-bloggers editor) Tal Galili just published the answers to a question many R users have asked: *which are the most popular R packages*? He wrote some R code to rank the top 100 packages by number of downloads. Here's the top 10:

The source data are the download logs from the RStudio CRAN mirror, whose logs RStudio team has helpfully made available in anonymized form for analysis. The Downloads column is the number of downloads of each package from January-May 2013, from a *single* CRAN mirror: it does not include downloads from the primary CRAN mirror or any of the 88 other CRAN mirrors. Just goes to show that there are at least 84,000 R users using this mirror alone (and most likely many more: not every R user installs a CRAN package). And as Ramnath Vaidyanathan shows in the map below, those R users are distributed all around the world:

If you're an R package author, you may be interested to know how often your package has been downloaded. Tal Gallili provides some code to answer that question as well. For example, here are the daily downloads for the Revolution Analytics contributed pacakage foreach:
